Removing cold restart tracking

[emawby]

Description

One Line Summary

Removing our call to track cold restarts via the /track endpoint

Details

Once User Model is released we will use a new end point for getting IAMs, and our old SDK versions will still be gathering this data. I am leaving the method to do the tracking in the SDK in case we want to add it back in the future, but it is no longer being called.

Motivation

We no longer need to be hitting our /track endpoint to track cold restarts. Our existing SDKs will get us data, and with user model we will change when IAMs are pulled down, which was the original reason for wanting to gather this data.

Scope

no longer hitting /track for cold restarts

Checklist

Overview

• I have filled out all REQUIRED sections above
• PR does one thing
  • If it is hard to explain how any codes changes are related to each other then it most likely needs to be more than one PR
• Any Public API changes are explained in the PR details and conform to existing APIs

Testing

• I have included test coverage for these changes, or explained why they are not needed
• All automated tests pass, or I explained why that is not possible
• I have personally tested this on my device, or explained why that is not possible

Final pass

• Code is as readable as possible.
  • Simplify with less code, followed by splitting up code into well named functions and variables, followed by adding comments to the code.
• I have reviewed this PR myself, ensuring it meets each checklist item
  • WIP (Work In Progress) is ok, but explain what is still in progress and what you would like feedback on. Start the PR title with "WIP" to indicate this.
